In your BIOS, under Advanced, the very last menu down the list should be for Intel® Rapid Storage Technology.

Please check to make sure that your Intel® Optane™ Memory is being displayed here along side with your other storage devices, if not, test installing it on the other M.2 slot and check again. Once it's shown, you should be able to proceed with the installation.

If it's not detected still, you may need to engage your motherboard manufacturer to find out and troubleshoot this from their end as well.

One thing I'm concerned with, despite your settings, the SSU report that you shared with us show Windows* as being run in Legacy BIOS mode. This doesn't make much sense as I can see that your system drive contains an EFI system partition (this means it is GPT, which only works in UEFI mode).

1. If you open a Run window (windows* key + R) and open MSInfo32.exe, under System Summary, does the BIOS Mode also show as legacy?

2. When you took those screenshots, was the Optane™ Memory physically installed? (it should show as an uninitialized drive, as a small NVMe* SSD).

DominicAlberts , thanks for your concern, but I have a different problem. Your Optane showed in Disk Management, but your HDD format was not compatible. In my case, the system is compatible, but the Optane is not recognized.

Based on this, your motherboard, BIOS version, and settings are all compatible and ready for Optane™ Memory. This leaves us with the following possibilities:

1. Your Optane™ Memory module is defective or DOA (dead on arrival). If within the original 30 days, you should be able to replace it through your place of purchase, if not, you may do so through our support team.2. There's something wrong with your BIOS. Since you're also working with ASUS* they should be able to confirm if this is the case.

Your motherboard and BIOS version are both compatible with Optane™ Memory, and your settings all seem to be in place.

I have an ASUS B250 Prime motherboard with Optane enabled and I have a suggestion you might want to try. I'm not sure, but I think I remember having to disable Fast Boot in the uefi bios to get the board to recognize the Optane module. I'm not positive but it is a very minor change to make and you can re-enable it easily after trying again to enable Optane.
